A woman who vowed to quit base jumping when she became ­pregnant died after she decided to make one final jump.

Extreme sports fan Wioletta Roslan, 37, died instantly after her parachute failed to open as she jumped from cliffs with her boyfriend Aleksander Domalewski.

Her mother Halina ­Zaniewska-Pettersson, had tried to talk Wioletta, who was four months pregnant, out of doing it.

“When she said she was going to do one last jump while pregnant I begged her not to go,” she said. “But she always wanted to carry on.

“Aleksander jumped at the same time as her and could only watch what happened.

“He told me that she desperately tried to get her parachute to open without success. It did not open and in the last moment she realised she wasn’t going to succeed. He told me that she had simply spread her arms and waited for the impact. I am totally devastated and shocked.”

Wioletta had travelled the world as a professional base jumper after taking up skydiving when she was 19.

She said that it made her feel alive and that there were no limits to life. “Even if the things I enjoy doing may be seen as scary, I love it,” she’d said previously.

Her final jump was from a favourite spot near her home in Lauterbrunnental, Switzerland, where she had moved from her native Sweden.

Her mother added: “I was always terrified every time I knew that she was doing a jump and kept expecting the worst.”

“I pleaded with her so often to give it up but she didn’t listen to me and now it’s too late.”
